fyz'penor:

bolts by which they can be secured against the boiler-shell.

The ends of these heads should be removable for purposes of cleaning out the chambers or removing and replacing the pipes B, or to facilitate inspection of the pipes and passages. By taking oft' the ends B4 of both heads the inside pipes or passages can be inspected for their entire length from either end of the boiler. It' one head is made a duplicate of the other, the connectiiig-pipes C and E maybe changed from one end of the boiler to the other; or the connection of the feedpump and the filtering device with the heater can be made at either end, as most convenient. In such case the openings in the partition of that head to which the connections are made will be closed by plugs h, provided for the purpose.

The filtering-chamber has a waste-pipe, I, leading Afrom the bottom for carrying off the sediment and other matter when the filter being cleaned out. rlhe boiler-pressure can be used for this purpose at such timeby shutting off the feed, closing the stop-valve XV in the pipe E, and letting off theboiler-pressure back through the pipe li. The loop Tin this pipe is provided for cutting out the checkvalve V. This operation is intended to clean the filtering medium in the chamber by reversing the travel of the water thro ugh it; but the sediment or precipitations collecting in the bottom of' the chamber around the inletpipe may be blown off at any time by opening the pipe to the atmosphere.

The capacity of the heating device may be enlarged by increasing the number of pipes, as shown in Figs. 2 and 3 of the drawings.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A feed-water-purifying apparatus consisting of a water-heating device located inside the boiler, by which the heat within the steam-generating space is utilized for raising' the temperature of the feed-water, said heating device consisting of the horizontal pipes or passages connected by the heads or chambers, arranged and constructed as set forth, a iiltering device located outside the boiler, and suitable pipes with valves connecting the heating device with the feed-pump and with the :filtering device, and also the filtering device With the stcam-generatii1g space of the boiler, whereby the feed-water is caused to pass through the heating device and then outside the boiler into and through the iiltering device before being delivered into the boiler-water, substantially as described, for operation as setl forth.

2. In a feed-water heating and purifying apparatus for steam-boilers, a heating device located within the boiler and connected with the feed-pump outside, said heating device consisting of the horizontal pipes connected by the heads or chambers, arranged and constructed as described, a conducting-pipe leading from said heater outside the boiler and adapted to deliver the feed-water therefrom into the boiler-water, and a filtering device interposed in the length of said pipe between the heater and the filter, in combination, substantially as described, the connections between feed-pump and heater and between filter and heater having the necessary valves for controlling the feed-water, as set forth.

3. In combination with a steam-boiler, pipes or passages B, which extend through the steam-generating space of the boiler to the outside, the connecting heads or chambers B .32, by which said pipes or passages are made to form a return-passage, and suitable pipes by which one end of said return-passage is connected with the feed-pump and the other end with the water room or space in the boiler, substantially as described.

4. The combination of water tubes or passages inside a boiler and extending to the outside tlufough the shell thereof, and connecting heads or chambers B B2, having separate compartments, of which those in one head are in communication with each other through an openin or openings, ZJ, and those in the other head have no direct connection, but are connected by suitable pipes or passages, the one with the feed-pump and the other with the water-room of the boiler, substantially as described.

5. In combination with a steam-boiler, water-heating tubes or passages B, extending through the boiler-space to the outside, the connecting heads or chambers B B2, by which said pipes are made to form areturn-passage, a feed-water pipe connecting one end of said heater with the feed-pump, a pipe connecting the other end with a filtering-chamber outside the boiler having a filtering diaphragm or partition, a pipe connecting said filter with the water room or space of the boiler, and a blow-off or waste pipe leading from the iiltering-chamber, substantially as described, for operation as set forth.

6. A feed-water-purifying apparatus for steam-boilers, consisting of the water-heating tubes or passages leading into and out of the boiler, the connect-in g heads or chambers B B2, having separate compartments, a feedwater-supply pipe, a steam-pipe, a iilteringchamber divided by a iiltering diaphragm or partition, a pipe connecting the compartment on one side of the partition with the heating device in the boiler, and the water room or space within the boiler with the other compartment, a blow-off or waste pipe, and suitable valves in said pipes for controlling the flow and circulation of the water directing the boiler-pressure through the apparatus, substantially as described, for operation as set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
